Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and in particular to a high-efficiency heat treatment device for screw production. Background Technology

[0002] Screws, as a standard fastener, are widely used in various industries such as machinery, construction, and electronics. To improve the mechanical properties of screws, such as hardness, strength, and wear resistance, heat treatment is an indispensable key process in their production.

[0003] In large-scale screw production, screws manufactured in previous processes are typically in a bulk, disordered state. Before entering the heat treatment furnace for processing, these scattered screws need to be loaded and conveyed to the furnace opening. The efficiency and stability of this loading and conveying process directly affect the smoothness of the entire heat treatment process and the final product quality.

[0004] In existing technical solutions, the screw feeding and sorting processes are often not highly automated, making it difficult to match the high-efficiency processing capacity of heat treatment furnaces. Some methods rely on manual loading of screws into hoppers in batches, which are then conveyed into the furnace by a conveyor. This method is not only labor-intensive and inefficient, but also makes it difficult to ensure the continuity and uniformity of feeding, easily leading to uneven heating of the workpieces inside the furnace. Other solutions use semi-automatic devices such as vibratory feeders for sorting, but when processing large quantities of screws, problems such as blockages, jamming, or poor discharge are still prone to occur, causing the entire automated production line to stop and forming a bottleneck that restricts overall production efficiency.

[0005] Therefore, how to quickly and automatically arrange bulk screws in an orderly manner and seamlessly connect them with the feeding process of the heat treatment furnace is a technical problem that urgently needs to be solved in the current screw production field to improve the overall efficiency of the heat treatment process.

[0006] Therefore, this utility model proposes a high-efficiency heat treatment device for screw production to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a high-efficiency heat treatment device for screw production, which aims to improve the problems of low automation in the feeding and distributing process of existing screw production heat treatment devices, difficulty in continuous and efficient coordination with the heat treatment process, and thus affecting the overall production efficiency.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A high-efficiency heat treatment apparatus for screw production includes a machine body, a conveyor belt and a heat treatment furnace with a furnace door; as well as a material distribution mechanism and a lifting mechanism.

[0010] The conveyor belt and heat treatment furnace are mounted on the machine body.

[0011] Furthermore, the material distribution mechanism is located between the discharge end of the conveyor belt and the inlet of the heat treatment furnace, while the lifting mechanism is combined with the furnace door of the heat treatment furnace in a drivable connection to drive the furnace door to lift.

[0012] Preferably, the material distribution mechanism includes a first cylinder, a first push block and a second push block fixedly connected to the piston rod of the first cylinder via a first connecting block, a rotating wheel, a rotating shaft, and a material distribution plate; the rotating wheel is rotatably mounted on the rotating shaft, and after being sequentially rotatably connected via the second connecting block, the first push rod, and the connecting plate, it is linked to the material distribution plate.

[0013] Preferably, the material dispensing mechanism further includes a slide rail and a slider; the slide rail is fixed to the machine body, and the slider is fixed to the bottom of the first push block and the second push block, and slides in cooperation with the slide rail.

[0014] Preferably, the material distribution mechanism further includes a spring, with both ends of the spring connected to the first push rod and the fixed part of the machine body, respectively.

[0015] Preferably, the material distribution mechanism further includes a top plate, a first support frame, and a second support frame for supporting its internal components.

[0016] Preferably, the lifting mechanism includes a second air pump, a second push rod, and a third connecting block; the second push rod is driven by the second air pump and is driven to connect to the furnace door through the third connecting block.

[0017] Preferably, the lifting mechanism further includes a connecting frame, which is fixedly connected to the furnace door, and the third connecting block is fixedly connected to the connecting frame.

[0018] Preferably, the lifting mechanism further includes a door frame and a sliding groove formed on the inner wall of the door frame, and the side edge of the furnace door slides in conjunction with the sliding groove.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by setting up a material distribution mechanism driven by a cylinder and combining linear reciprocating motion with a linkage mechanism, the problem of low efficiency and difficulty in continuous automation of the material distribution process in the prior art when heat treating bulk parts such as screws is solved. The material distribution process relies on manual labor, is inefficient, and is difficult to achieve continuous automation. It achieves the technical effect of quickly and orderly separating and arranging screws, providing a prerequisite for subsequent continuous heat treatment, and significantly improving the automation level and production efficiency of the screw distribution process.

[0021] 2. In this utility model, by coordinating the material distribution mechanism with the lifting mechanism that automatically controls the opening and closing of the furnace door, the problems of poor connection between various processes and low overall automation in the prior art, which lead to production interruptions and difficulty in ensuring the consistency of product heat treatment quality, are solved. This achieves the integration of material distribution, furnace feeding, heat treatment, and furnace unloading into a continuous and stable automated operation process, which not only greatly improves the overall production efficiency, but also ensures the stability and consistency of screw heat treatment quality through standardized process control.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 4 This utility model provides a high-efficiency heat treatment device for screw production, which aims to solve the problems of low feeding and dispensing efficiency and difficulty in achieving automated continuous production in the prior art.

[0031] like Figure 1 As shown, the high-efficiency heat treatment device for screw production includes a machine body 1, a conveyor belt 5 mounted on the machine body 1, and a heat treatment furnace 4 with a furnace door 302. The machine body 1 provides the installation and support foundation for the entire device. The conveyor belt 5 is used to transport screws to be treated and those that have already been treated. The heat treatment furnace 4 is used to perform heat treatment on the screws. The core of this device is that it also includes a material distribution mechanism 2 and a lifting mechanism 3. The material distribution mechanism 2 is located between the discharge end of the conveyor belt 5 and the inlet of the heat treatment furnace 4. It is used to orderly distribute the screws transported by the conveyor belt 5, preparing them for efficient entry into the heat treatment furnace 4. The lifting mechanism 3 is drivably connected to the furnace door 302 and is used to automatically drive the furnace door 302 to rise and fall according to the rhythm of material distribution and conveying, thereby realizing automated control of feeding and discharging.

[0032] Specifically, the material distribution mechanism 2 and the lifting mechanism 3 work together to form a continuous automated process for conveying, sorting, feeding into the furnace, heat treatment, and unloading the screws; (Refer to...) Figure 2 and Figure 3The material distribution mechanism 2 includes a first cylinder 202 as a power source, and a first push block 206 and a second push block 207 driven by the first cylinder 202. The piston rod of the first cylinder 202 is fixedly connected to the first push block 206 and the second push block 207 through a first connecting block 203, thereby accurately transmitting the linear motion of the first cylinder 202 to the first push block 206 and the second push block 207. To ensure that the first push block 206 and the second push block 207 can reciprocate smoothly, the material distribution mechanism 2 also includes a slide rail 204 fixed to the machine body 1 and a slider 205. The slider 205 is fixed to the bottom of the first push block 206 and the second push block 207, and the slider 205 slides in cooperation with the slide rail 204. The material distribution mechanism 2 also includes a rotating wheel 210, a rotating shaft 211, and a material distribution plate 216 that ultimately performs the material distribution action. The rotating wheel 210 is rotatably mounted on the rotating shaft. On 211, its rotation is driven by the movement of the first push block 206 and the second push block 207. After the rotating wheel 210 is sequentially rotated and connected by a second connecting block 212, a first push rod 213 and a connecting plate 215, it forms a linkage connection with the material distribution plate 216, which ultimately converts the linear motion generated by the first cylinder 202 into the precise material distribution action of the material distribution plate 216, thereby arranging the screws. In order to assist the movement of the first push rod 213, the material distribution mechanism 2 also includes a spring 214. The two ends of the spring 214 are respectively connected to the first push rod 213 and the fixed part of the machine body 1, which is used to provide a reset force for the first push rod 213 and ensure that the linkage mechanism can be reliably reset. In order to ensure the overall structural stability of the material distribution mechanism 2, it also includes a top plate 201, a first support frame 208 and a second support frame 209 for supporting its internal components. These support components provide a rigid foundation for the smooth operation of the entire material distribution mechanism 2.

[0033] After the material distribution mechanism 2 completes the material distribution, the lifting mechanism 3 starts working to open the furnace door 302, allowing the distributed screws to enter the heat treatment furnace 4; refer to Figure 4The lifting mechanism 3 includes a second air pump 304 as a power source, a second push rod 305, and a third connecting block 306. The second push rod 305 is driven by the second air pump 304 and forms a driving connection with the furnace door 302 through the third connecting block 306, transmitting the power generated by the second air pump 304 to the furnace door 302 to drive its lifting. To achieve reliable force transmission, the lifting mechanism 3 also includes a connecting frame 303, which is fixedly connected to the furnace door 302, while the third connecting block 306 is fixedly connected to the connecting frame 303. Through this connection method, the lifting motion of the second push rod 305 can be stably converted into the lifting motion of the furnace door 302. To ensure the stability and guidance of the furnace door 302 during the lifting process, the lifting mechanism 3 also includes a door frame 301 and a slide groove 307 opened on the inner wall of the door frame 301. The door frame 301 surrounds the feed inlet of the heat treatment furnace 4. The side edge of the furnace door 302 slides in cooperation with the slide groove 307, so that the furnace door 302 can only move vertically and precisely along the trajectory defined by the slide groove 307, avoiding jamming or shaking.

[0034] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the specific structural cooperation and linkage relationship formed between the components inside the material distribution mechanism 2. By transforming the simple linear pneumatic drive into a complex and precise material distribution action, the efficient and orderly sorting of screws is achieved. The technical solution is realized through the specific structural cooperation and connection relationship formed between the first cylinder 202, the first push block 206, the second push block 207, the rotating wheel 210 and the material distribution plate 216.

[0035] Please refer to the following carefully. Figure 2 and Figure 3 The core structure will be described in detail below:

[0036] The material dispensing mechanism 2 outputs linear reciprocating motion through the first cylinder 202. This motion is transmitted to the first push block 206 and the second push block 207 through the first connecting block 203. To ensure the stability and accuracy of this linear motion, sliders 205 are fixedly connected to the bottom of the first push block 206 and the second push block 207. At the same time, slide rails 204 are fixedly installed at the corresponding positions on the machine body 1. The sliders 205 and the slide rails 204 form a sliding fit. This fit structure provides precise guidance and limit for the movement of the first push block 206 and the second push block 207, ensuring high stability and anti-deflection capability during the movement.

[0037] Meanwhile, the material distribution mechanism 2 is equipped with a linkage mechanism that converts linear motion into material distribution action. The core of this linkage mechanism is the rotating wheel 210 and the rotating shaft 211 that rotatably supports the rotating wheel 210. The rotating wheel 210 is connected to the first pushing block 206 or the second pushing block 207 through a gear rack or cam, so that the linear motion of the first pushing block 206 and the second pushing block 207 can drive the rotating wheel 210 to rotate around the rotating shaft 211. The rotation of the rotating wheel 210 is transmitted to the material distribution plate 216 through a linkage assembly, which includes a second connecting block 212, a first pushing rod 213 and a connecting plate. 215; Specifically, one end of the second connecting block 212 is rotatably connected to the eccentric position of the rotating wheel 210, and the other end is rotatably connected to one end of the first push rod 213. The other end of the first push rod 213 is linked to the material distribution plate 216 through the connecting plate 215. When the first cylinder 202 works, the first push block 206 and the second push block 207 drive the rotating wheel 210 to rotate. The rotation of the rotating wheel 210 then drives the material distribution plate 216 to generate a preset complex motion trajectory for separating and straightening screws through the linkage mechanism composed of the second connecting block 212 and the first push rod 213, thereby efficiently completing the material distribution operation.

[0038] For the power source that drives the movement of this device, the material distribution mechanism 2 adopts the first cylinder 202 and the lifting mechanism 3 adopts the second air pump 304. The specific internal structure and working principle of these pneumatic components are well known in the field and will not be described in detail here.

[0039] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0040] As a preferred embodiment, to further improve the stability of the reciprocating motion components in the material distribution mechanism 2, please refer to... Figure 2 and Figure 3 A slider 205 is fixedly connected to the bottom of the first push block 206 and the second push block 207. At the same time, a slide rail 204 is fixedly installed on the body 1 at the corresponding position of the slider 205. The internal rolling element of the slider 205 forms a rolling sliding fit with the guide surface of the slide rail 204. This high-precision linear guide structure can significantly reduce motion friction and provide stable and reliable guidance for the first push block 206 and the second push block 207.

[0041] As a preferred embodiment, to ensure the reliable reset of the linkage mechanism in the material distribution mechanism 2, please refer to... Figure 3A spring 214 is connected between the middle of the first push rod 213 and a fixed point of the machine body 1. The spring 214 is preferably a tension spring. When the first push rod 213 moves, it is stretched to store elastic energy. When the driving force is removed, the contraction force of the spring 214 can help the first push rod 213 and the material distribution plate 216 and other components linked with it to quickly and accurately return to the initial position, in preparation for the next material distribution cycle.

[0042] As a preferred embodiment, to provide a stable mounting frame for the material distribution mechanism 2, please refer to... Figure 2 The material distribution mechanism 2 also includes a top plate 201, a first support frame 208, and a second support frame 209. The bottom ends of the first support frame 208 and the second support frame 209 are fixed to the machine body 1, and the top plate 201 is fixedly connected to the top of the first support frame 208 and the second support frame 209, thus forming a sturdy frame structure. The first cylinder 202, the rotating shaft 211, and other internal working parts are all installed on this frame structure.

[0043] As a preferred embodiment, in order to achieve stable and reliable driving of the furnace door 302, please refer to... Figure 4 In the lifting mechanism 3, the second push rod 305, the third connecting block 306, and the connecting frame 303 constitute a rigid driving assembly. The connecting frame 303 is firmly fixed to the outer surface of the furnace door 302 by welding or bolts, and the third connecting block 306 is fixedly connected to the connecting frame 303. The second air pump 304 drives the second push rod 305, and the end of the second push rod 305 is fixedly connected to the third connecting block 306, thereby transmitting the driving force of the second air pump 304 to the furnace door 302 without damage.

[0044] As a preferred embodiment, to ensure smooth and precise guidance of the furnace door 302 during lifting and lowering, please refer to... Figure 4 A door frame 301 is fixedly installed at the furnace opening of the heat treatment furnace 4. Slide grooves 307 are respectively machined on the two vertical inner side walls of the door frame 301. The two side edges of the furnace door 302 are correspondingly provided with guide flanges that are adapted to the shape and size of the slide grooves 307. The guide flanges are embedded in the slide grooves 307 and can slide along their length. This structure ensures that the furnace door 302 is firmly constrained on the preset vertical trajectory throughout the entire lifting process, effectively preventing tilting, jamming and other problems during the opening or closing process.

[0045] Working principle: In the initial state, the screw to be processed is placed on the conveyor belt 5. The conveyor belt 5 starts and transports the screw to the sorting mechanism 2. When the screw reaches the designated position, the first cylinder 202 of the sorting mechanism 2 starts to work. Its piston rod drives the first push block 206 and the second push block 207 to perform linear reciprocating motion under the guidance of the slide rail 204 and the slider 205 through the first connecting block 203. Since there is a driving connection between the first push block 206 and the second push block 207 and the rotating wheel 210, the linear motion of the first push block 206 and the second push block 207 drives the rotating wheel 210 to rotate around the rotating shaft 211.

[0046] The rotation of the wheel 210 drives the material distribution plate 216 to perform a pre-set complex movement for sorting and separating screws through a linkage mechanism consisting of the second connecting block 212, the first push rod 213 and the connecting plate 215. At the same time, the spring 214 provides a reliable restoring force during the process. The entire material distribution action is completed within a stable frame consisting of the top plate 201, the first support frame 208 and the second support frame 209, thereby realizing the rapid and orderly material distribution and arrangement of the disordered screws on the conveyor belt 5.

[0047] After the material distribution mechanism 2 completes the orderly arrangement of the screws, the second air pump 304 of the lifting mechanism 3 is started, driving the second push rod 305 to move upward; the second push rod 305 transmits power to the furnace door 302 through the third connecting block 306 and the connecting frame 303; since the side edge of the furnace door 302 forms a precise sliding fit with the sliding groove 307 on the door frame 301, the furnace door 302 is driven to rise smoothly along the trajectory of the sliding groove 307, opening the feed port of the heat treatment furnace 4; at this time, the screws that have been distributed are sent into the heat treatment furnace 4 via the conveyor belt 5.

[0048] After the screws enter the heat treatment furnace 4, the second air pump 304 reverses its operation, driving the furnace door 302 to descend smoothly and close, and the heat treatment furnace 4 begins to heat treat the screws. After the heat treatment is completed, the lifting mechanism 3 operates again to open the furnace door 302, and the conveyor belt 5 sends out the treated screws, thus completing a complete automated processing cycle. Through this automated synergy between the material distribution mechanism 2 and the lifting mechanism 3, this utility model solves the problems of low material distribution efficiency and inability to produce continuously in the prior art for screw heat treatment, and significantly improves production efficiency.
